The 'Horrible Bosses' star admits she has learned to accept her natural look for what it is after a boyfriend told her she looked better without any make up.

She told InStyle magazine: "Why would you want to [have Botox and] atrophy muscles anyway? If you don't work out, eventually everything drops.

"Less is more. [It's important to] peel away those layers. I had a boyfriend who always said I looked better without makeup.

"It took me a while to feel comfortable enough to remove that armour, but I eventually realised he was right."

Meanwhile, the 47-year-old actress - who is married to Justin Theroux - previously penned an essay where she slammed the "objectification and scrutiny" of women.

She wrote: "I’m fed up with the sport-like scrutiny and body shaming that occurs daily under the guise of 'journalism,' the 'First Amendment' and 'celebrity news.'

"Every day my husband and I are harassed by dozens of aggressive photographers staked outside our home who will go to shocking lengths to obtain any kind of photo, even if it means endangering us or the unlucky pedestrians who happen to be nearby. But setting aside the public safety aspect, I want to focus on the bigger picture of what this insane tabloid ritual represents to all of us.

"The objectification and scrutiny we put women through is absurd and disturbing. The way I am portrayed by the media is simply a reflection of how we see and portray women in general, measured against some warped standard of beauty.

"Sometimes cultural standards just need a different perspective so we can see them for what they really are - a collective acceptance ... a subconscious agreement. We are in charge of our agreement. Little girls everywhere are absorbing our agreement, passive or otherwise."
